Caracterização da dinâmica térmico-hídrica do solo em cultivo da palma de óleo com híbridos interespecíficos (Elaeis guineensis x Elaeis oleifera) no leste da Amazônia.

Abstract

Analyzes made by the Intergovernmental Panel on Climate Change (IPCC) suggest that the increase in concentration of greenhouse gases (GHG), carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) will reach all sectors of human activity and the ecosystems, causing the increase in the temperature of the planet (IPCC, 2013). Also point out, that there will be an increase in rainfall with high rainfall and decrease in the regions that they are suffering from a shortage of water, in addition to increase the frequency and intensity of extreme events, such as floods, hurricanes and prolonged droughts. In this context, the state of Para appears in potential for expansion of the culture of palm oil, especially after the ecological economic Zoning of palma in Brazil, prohibiting planting in areas of native forest which allows the activity to grow without causing deforestation. This study is part of a job that encompasses all aspects of the development and production of palm oil, which includes the assessment of dynamic thermal-water in soils with planting of palm oil with interspecific hybrids (E. Guinea X E. oleífera) .this study aimed to evaluate the dynamic thermal-water, daily and seasonal, in soils with planting of palm oil with interspecific hybrids (E. Guinea X E. oleífera). It was concluded that all profiles showed a reduction in volumetric content of water in the soil at a depth of 20 cm, it is concluded that the root system of palm oil is concentrated at this depth.
